I claim as my invention:

1. The combination of an engine cylinder provided with inlet and exhaustports, a piston operative in the cylinder, a valve embodying portedsleeves, cooperative with the ports of'the cylinder, and means foroscillating one of said sleeves and for continuously rotating anotherfor controlling said cylinder ports.

2. Thecombination of an engine cylinder provided with inlet and exhaustports, a piston operative therein, and a valve embodying a pair ofnested sleeves having ports cooperative with those of the cylinder, andmeans for oscillating one of the sleeves and for continuously rotatingthe other sleeve to control the cylinder ports.

3. In an internal combustion engine, the combination of a cylinderprovided with inlet and exhaust ports and -a piston operative therein, avalve embodying a pair 0 ported members cooperative with the cylinderports, and means for continuously rotating One of said members and foroscillating the other member to control the cylinder ports.

4. In an internal combustion engine, the combination of a cylinderprovided with inlet and exhaust ports communicating with the compressionchamber thereof, and having a piston operative therein, a valveembodying nested sleeves mounted in the con1- pression chamber 'of thecylinder and having ports cooperat've with those of the cylinder, andmeans for revolving one of said sleeves and for oscillating the othersleeve to control the cylinder ports.

5. In an internal combustion engine, the combination of a cylinderprovided with inlet and exhaust ports communicating with the compressionchamber thereof, and hav- 1 ing a piston operative therein, a valveembodying nested sleeves mounted in the compression chamber of thecylinder and having similarly-inclined helically-extending portscooperative with the cylinder ports, 5 and means for revolving oneof'the sleeves continuously in one direction and for oscillating theother sleeve. alternately in reverse directions to control the cylinderports.

6. In an internal combustion engine, the 0 combination of a cylinderprovided with in let and exhaust ports, and a piston operative therein,a valve embodying a pair o nested sleeves one having a pair of portsadapted to register alternately with the in- 1st nd exhaust ports of thecylinder, and

haust ports of the c linder, are inclined or 'arranged helically, thehelical port of the inner sleeve being inclined in the same directionwith those in the outer sleeve and the cylinder ports.

In operation, the two-ported sleeve oscillates, while the single-portedsleeve rotates emitinuously, the latter having a clockwise movement inthe present instance, as indicated by the arrow. Different means may beused for suitably operating the valve sleeves, they being provided inthe construction shown with telescoped or sleeved shafts l4 and 15 whichare connected by the webs 1t and 17 to the respective sleeves. Theoscillatory outer sleeve is provided with a crank 18 and thecontinuously rotating sleeve is operated, for example,'by a gear 12)lived to the shaft or stem thereof and cooperating with a gear 20, thelatter being fixed to a suitably journaled shaft 21, which isoperatively connected by gearing 22 to a shaft 23'. A. common timingshaft 24 operati n g at one-half the engine shaft speed may serve tooperate the valve sleeves or members, the shaft 23 being connectedthereto by the gearing 25, while an eccentric 26 on the timing shaftoperates a pitman 27, which latter is connected to the crank arm 18 forthe oscillating valve sleeve.

The operation ofthe engine on the Wellknown four-cycle principle may bedescribed briefly as follows: During the suction stroke of the pistonwhich serves to introduce a charge into the cylinder, the port 10 of theoscillating outer sleeve and the port of the continuously revolvinginner sleeve register .with the inlet port t of the cylinder, theexhaustport 5 being then closed, as shown in Fig. 5. During the next iii-strokeof the piston which causes compression of the charge, the ports 10 and13 are both beyond the inlet port a and hence this port and also theexhaust port will-be closed by the solid portions of the sleeves, asshown in Fig. 6. During the following out-stroke of the. piston underthe power of the explosion, the inlet and exhaust ports sleeves, asshown in Fig. 7, and when this power stroke of the piston has beencompleted the port 13- of the inner sleeve and also the port- 11 of theoscillatoryv outer the other sleeve having a single port adaptmy hand inpresence of two subscribing wited1 to register atefinatelly with theinlet and nesses. I ex must ports 0 l e cy inder, and means forcontinuously rotating one of said sleeves and MATTHEW AMES 5 oscillatingthe other sleeve to control the Witnesses: cylinder ports.
